9 <H3>SYNOPSIS</H3><TT>llvm-abcd [options] [filename]</TT>
10 <H3>DESCRIPTION</H3>The <TT>llvm-abcd</TT> command is a small utility for analyzing
11 bytecode files. The <TT>abcd</TT> acronym stands for <u>a</u>nalysis of
12 <u>b</u>yte<u>c</u>ode <u>d</u>isplayer. The tool reads a bytecode file (such as
13 generated with the <TT>llvm-abcd</TT> tool) and produces statistical and low level
14 bytecode format dumps. This tool is probably not of much interest or utility except
15 for those working directly with the bytecode format. Most LLVM users can just ignore
17 <P>If filename is omitted or is -, then <TT>llvm-abcd</TT> reads its input from
18 standard input. This is useful for combining <TT>llvm-abcd</TT> in a pipeline.
22 <LI>-nodetails <BR>Causes <TT>llvm-abcd</TT> to abbreviate its output by writing
23 out only a module level summary. The details for individual functions are not
26 <LI>-dump <BR>Causes <TT>llvm-abcd</TT> to dump the bytecode in a human readable
27 format. This format is significantly different from LLVM assembly and provides
28 details about the encoding of the bytecode file.
30 <LI>-verify <BR>Causes <TT>llvm-abcd</TT> to verify the module produced by
31 by reading the bytecode. This ensures that the statistics generated are reliable.
33 <LI>-help <BR>Print a summary of command line options.
35 <H3>EXIT STATUS</H3>If <TT>llvm-abcd</TT> succeeds, it will exit with 0.
36 Otherwise, if an error occurs, it will exit with a non-zero value, usually 1.
